Novel N-substituted phthalimides (2-substituted 1H-isoindole-1,3- diones) were prepared, and their effects on tumor necrosis factor-alpha (TNF- alpha) production by human leukemia cell line HL-60 stimulated with 12-O- tetradecanoylphorbol 13-acetate (TPA) or okadaic acid (OA) were examined. A structure-activity relationship study of the N-phenylphthalimides and N- benzylphthalimides revealed that their enhancing effect on TPA-induced TNF- alpha production by HL-60 cells and their inhibiting effect on OA-induced TNF- alpha production by HL-60 cells are only partially correlated.

A novel “site decompression technique” that takes advantage of specific pressure relaxation effects in cryogenic noble gas matrices was applied in a spectroscopic investigation of the two title compounds, resulting in virtually background-free, complete, high-resolution IR spectra with line widths of ca. 0.1 cm-1. The compounds were prepared photochemically in Ar and Ne matrices and, together with the related intermediates, fluorinated benzocyclopropenone and cyclopentadienylideneketene, characterized by IR and UV-visible absorption spectroscopy. Weak IR absorption bands observed at 1878 cm-1 for perfluoro-o-benzyne and at 1866 cm-1 for 3-fluoro-o-benzyne were assigned to CC triple bond stretching vibrations, corresponding to the transition at 1846 cm-1 in the parent o-benzyne. The application of polarization spectroscopy on photooriented samples led to the determination of transition moment directions for most of the observed vibrational transitions. Absolute IR absorption intensities were also obtained. The assignments of the observed transitions were supported by the results of B3LYP/cc-pVDZ quantum chemical calculations.

Vesicular glutamate transporters (VGLUTs) allow the loading of presynaptic glutamate vesicles and thus play a critical role in glutamatergic synaptic transmission. Rose Bengal (RB) is the most potent known VGLUT inhibitor (K i 25 nM); therefore we designed, synthesized and tested in brain preparations, a series of analogs based on this scaffold. We showed that among the two tautomers of RB, the carboxylic and not the lactonic form is active against VGLUTs and generated a pharmacophore model to determine the minimal structure requirements. We also tested RB specificity in other neurotransmitter uptake systems. RB proved to potently inhibit VMAT (Ki 64 nM) but weakly VACHT (Ki >9.7 muM) and may be a useful tool in glutamate/acetylcholine co-transmission studies.

When acted upon by HF/SbF5 at 95 C, carbonyl groups of perfluorinated acetophenone (10), 3,4-dihydronaphthalen-1(2H)-one (8), 2,3-dihydronaphthalene-1,4-dione (9), benzocyclobutenone (6), benzocyclobutenedione (7) and indan-1-one (1) are converted into difluoromethylene groups to give the corresponding perfluoroaromatic products. Perfluoroindan-2-one (5), under the same conditions, is transformed to bis(perfluoroindan-2-yl) ether (21). On heating with HF/SbF5, perfluoroindan-1,3-dione (2) isomerizes into perfluoro-3-methylenephthalide (4) at 95 C, and gives 4,5,6,7-tetrafluoro-3-trifluoromethyl-phthalide (14) at 130 C. Compound 4 in the absence of a solvent dimerizes giving perfluorodispiro[phthalide-3,1?-cyclobutane-2?,3?-phthalide] (18), and when heated with SbF5 at 130 C, it is converted into perfluoro-3-methylphthalide (3). When acted upon by HF/SbF5 at 95 C, perfluorinated benzoic acid (12) and phthalic anhydride (13) give the corresponding products with trifluoromethyl groups.

Polymers of intrinsic microporosity (PIMs) are porous polymers with rigid ladder-type chain structures. Synthesizing these polymers usually involves the step polymerization of two types of monomer, namely, active fluorine-substituted aromatic ring monomers and phenolic monomers. Herein, we report a new PIMs preparation method using self-synthesized fluorinated monomers and common monomer 5,5?,6,6?-tetrahydroxy-3,3,3?,3?-tetramethyl spirobisindane. The fluorinated monomers were synthesized through the imidization of tetrafluorophthalic anhydride and aromatic diamines. The resulting PIMs served as a support for palladium, with the formed catalyst showing potential for application in the Suzuki-Miyaura coupling reaction.

(Chemical Equation Presented) 9,10-Dichlorooctafluoroanthracene (1) was synthesized from commercially available tetrafluorophthalic acid by an optimized solution-phase route. To establish 1 as a synthon for n-type organic semiconductors, the compound was reacted with phenylboronic acid under modified Suzuki-Miyaura coupling conditions to generate octafluoro-9,10- diphenylanthracene (7) in high yield. Cyclic voltammetry and X-ray crystallography indicate that 7 has a stabilized LUMO energy level and exhibits extended pi stacking, which should lead to efficient electron transport in solid-state devices. 1,2,3,4,5,6,7,8-Octafluoroanthracene (2) was also synthesized as a potential n-type building block, but suitable C-C coupling conditions for this compound were not found, and 2 could not be converted into 9,10-dibromooctafluoroanthracene or octafluoro-9,10-diiodoanthracene.

We report the synthesis and characterization of perfluoropentacene as an n-type semiconductor for organic field-effect transistors (OFETs). Perfluoropentacene is a planar and crystalline material that adopts a herringbone structure as observed for pentacene. OFETs with perfluoropentacene were constructed using top-contact geometry, and an electron mobility of 0.11 cm2 V-1 s-1 was observed. Bipolar OFETs with perfluoropentacene and pentacene function at both negative and positive gate voltages. The improved p-n junctions are probably due to the similar d-spacings of both acenes. Complementary inverter circuits were fabricated, and the transfer characteristics exhibit a sharp inversion of the output signal with a high-voltage gain. Copyright
